engine turns over but does not start no spark no fuel replaced cps,plugs,plug wires,and all fuses.gauges come on inspection light comes on car turns but no start.next thought is ecu/dme.i dont think any of the relays are getting any power jumperd all the relay sockets(30/87) still no power on any of them.....im stuck as what to do next other than ecu....please help im a true e30 fan will never sell this ride!

Sorry to hear it.  Electrical problems are always a PITA.  Might be quicker to grab a JY harness...let us know what you find.

Did you get a wiring harness with the new (used) motor or did you splice everything when you installed it ?

From what I hear that was a upgraded harness for the AFM.. Apparently the factory harness would let water leak into it, so they used to this seal the plug better (This what I have read on other sites)...I have been running mine with this extension for over a year...No problems..

Yeah, it's a resistor pack to change the MAF signal to the DME.  I had water in mine & pulled it out.  BMW developed it to deal with rough idle for the early M42s.

Did you test the crank pos sensor for resistance?  I know you replaced it, but you'll have to eliminate problems to chase this one down.  If the ECU doesn't get the right signal it won't power the fuel pump.

Check the resistance and voltage at the coils. Also tap on the starter to see if it's sticking. If the V and Ohms are good as the coils (should be 0.8 +/- 0.1) then check voltage from the DME on the coil pins as well as the fuel pump. However, you should be able to hear the pump kick on when you turn on the car. If there is voltage for the pump at the DME, but you don't hear it turn on, check your connections at the pump. If the starter still doesn't engage after tapping, check the starter relay. If it's good inspect the wiring. If that is good, replace the starter or have it tested at the local autozone, kragen, napa, etc.

Check and report back.
